WINDOW-SCREEN.

I Specification of Letters Patent.

Patented Feb. 19, 19158.

To all whom it may concern:

Be it known that-I, ARTHUR'C. Scorn, a citizenofthe United States, and aresident of the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in lVindow-Screens, of which the following is a specification.

This invention relates to improvements in window screens and moreparticularly to the structure of, and the means for combining thescreens with the window frame.

Among the objects of this invention are:

To produce a sightly screen for windows which can remain apermanent-fixture, easily operated or removed and which permits easyaccess to the Window sashes for opening, closing or washing the same,irrespective of the particular type'of sliding or casement sashes;

To provide a screen which can be applied to the face of the windowcasing or within the inclosure of the same; I

To provide a screen which can he slid to the top of the window casing,to leave the lower half of the casing unscreened or viceversa; I

To provide a'screen the members of which are so hung that they can heslid up and down in the vertical plane or independently swung outward ontheir pivots fromthe plane of the window casing;

To providea screen comprising a plurality of overlapping frames, pivotedand guided within a single slot or groove in each side of the windowcasing;

To provide a screen which will permit'free access for the opening andclosing of the window sashes, with the minimum opening of the screen,to'reduce the possibility of flies or insects entering while the screenis thus opened;

To provide a screen with all the foregoing and other advantages, whichwill operate between the window casing and theconventional shade orcurtains usually attached to windows;

To provide means for stretching and securing the screen netting to itsframe by positive and permanent means, which will geous features which,with the foregoing,

will be set forth at length in the following description, where I shalloutline in full that form of invention selected for illustration in thedrawings accompanying and forming part of the present specification. Thenov city of the invention will be included in the claims succeeding saiddescription. From this, it will be apparentthat I donot restrict myselfto the showing made by said drawings and description, as I may adoptmany variations within the scope of my invention as expressed in saidclaims.

In the drawings:

Fig. 6" is a side elevation partially in cross section of the springpivot on the upper screen frame.

Fig. 7 is a fragmentary plan view from above'ofthe guide strip, having aguiding groove therein, into which issecured the i stop head for thelower screen frame. This view is partially in cross section, taken on'In detail, the construction consists of, a

conventional window casing structure, comprising the rabbeted j ambs 1,top plate 2,.the sill 3, the stoolt and the usual facings 5 and 6, stopsparting beads, etc., consistent with the type of Window to beaccommodated; for convenience in description this structure willhereinafter be referred to as the window casing.

The window casing is provided with the screen guides 77- on both sidesof the easing. These guides can also act as stops for the window sasheswhen properly applied. These guides are provided with a groove 8.

The screen comprisesv preferably two frames, upon which the netting 9 isstretched. The two top corners of the top screen are provided withsliding spring pivots comprising the pins 10, having the oblong frictionshoe or head 11 pivoted thereon.

The pins are surrounded by sleeves 12', having'one end crimped or turnedin as at 13, to form a seat or abutment for the end of the coil spring14, encircling the pin within the sleeve and expanding between theabutment 13 and the head 11 on the pin.

The heads 11 project beyond the lateral edges of, the screen frame adistance a trifle greater than the depth of the grooves 8, 4O

whenthe screen frames arein operative po sition in the casing.

The screen frame A, is assembled in the casing by inserting one of theheads 11 into 7 the groove 8, then tipping the plane of the screenhorizontally, at an angle to the vertical plane of the groove, to permitthe second head 11, to engage the groove on the opposite side of thecasing, the. screen frame is suspended within the casing by thefrictional upper corners of the frame B, in the, most.

desirable manner. The offset of the spring plate 17 is sufficient toallow the screen'B, to slide over the frame A. The spring tension of thespring plate 17 causes the heads 15 to frictionally engage the grooves88; thus suspended, both frames are free to i swing outward from theplane of the window casing, as illustrated by dotted lines in 1,25e,sss

. rests upon the stool 4:, behind the stop-fixtures '19 fixed uponopposite sidesof the casing and abutting the stop head 20; thusconstructed and assembled, the screen completely closes the opening ofthe window casing, to prevent the entrance of flies and insects, whichis the primary function of the screen, when the window is open.

To permit easy access for-them'anipula: tion of the .window'sashes, theframeB can be lifted by the handle 21, over the stop fixture 19and'lowered to the position shown in A Fig. 1 to permit access tothe'latch 22, in

the instance of a casement window or the frame A can be swung outward topermit access to the fixture 23, in the instance of a sliding sashwindow as illustrated in Fig.

2. The frame A can be lowered down he I hind the frame B orthe framesmaybe placed in many obvious relations to each other and the windowcasing. During the winter months when insect pests are not prevalentboth screen frames can easily be removed and stored away without leavingany unsightly attachments to disfigure the casings. The guide strips areof such simple construction that they are scarcely distinguishable fromthe molding trim of the window casing.

' It is preferableto mount the screens on the interior side of the casinto make their'application universally possible, irrespective of the formof sash, except in rare instances when casement or otherv forms ofsashesmay project into the room, when in the open position, then the screencan be placed on the exterior of the casing.

The available space on the interior side of a window casing is limited;therefore the type of screen frame indicated by this invention must berelatively thin, compact, light, well fitted and sightly.

The mechanical construction of the screen frame hereinafter described,fulfils the most exacting requirements of this art. The frames arecomposed of the wooden strips 2%, cut to lengths,;to form whenjoined,rectangular frames,approximately the conven-.

tional sizes of window casings. Mounted in the facing of the wlndowcasing as in Fig. 3, therange of variable widths of screen,

with respect to the widths of the window casing is considerable, whichpermits the screens to be made up in stock sizes; whereas the typeillustrated in Fig. 3 does not admit of such a wide variation in therelative sizes of casing and screen; some adjustability can be providedfor in this type, by making the guides 7, deep enough to permit ofripping off the excessive material in fitting the screen to the windowcasing.

The various steps in producing a screen frame in accordance with thisinvention, are substantially as follows:

First: The strips 24 are provided with the saw kerf or groove 25, thenmitered or otherwise joined at the four corners of the frame, so thatthe kerf 25 extends around the frame, a suitable distance back from theinner edge.

Second: Cut blanks of netting 9 of a dimension insuring that the edgethereof extends down into the kerf and part way back, are laid upon theframe.

Third: The angular metal reinforcing strips 26, provided with the barbs27, struck therefrom, are disposed on top of the'netting, the flange 28coinciding with the kerf 25. The 'securing points 29, also struck fromthe body of the strip serve the double purpose of leveling the strip tomaintain the flange in the plane of the kerf and to secure the strip tothe wood when forced into it.

Fourth: Thus assembled the reinforcing strips are forced down by a pressor otherwise, so that the flange 28 carries the slack of the edge of thenetting into the kerf, the barbs preventing the netting from slipping;whereby the netting is stretched taut in all four directions at once,insuring a drumlike tightness. The barbs and the securing points enterthe fiber of the wood and the flange 28 wedges into the kerf, allcooperating to secure the strips to the frame, which is materiallystrengthened by the addition of the reinforcing strips; but thereinforcing strips can be dispensed with, the netting being retained inthe kerf by its own engagement therewith.

Fifth: Toadd rigidity and finish to the frame the corners are reinforcedby an angular metal plate 30, bent back upon itself and having theangles 3. struck up therefrom, to inclose the corner of the frame towhich it is attached by the rivets 32 or otherwise. The return bend ofthis plate is provided with ahole to receive the leeve 13 or with screwholes, to receive the screws 3% for securing the spring plate 17, as thecase may be.

Having thus described this invention, what is claimed and desired tosecure by Letters Patent is:

1. A window screen including, grooved side guide-s attachable to windowcasings, a

screen frame, resilient pivots attached to the opposite upper corners ofsaid frame and slidable in said grooved side guides.

2. A window screen including side guides attachable to window casings, ascreen frame, resilient pivots attached to the opposite upper corners ofsaid frame, friction members attached tosaid pivots and slidable in saidguides.

8. A window screen including, side guides attachable to window casings aplurality of overlapping screen frames, resilient pivots attached to theopposite upper corners of each of said frames and slidable in saidguides.

4. In combination with a window casing having a single guide on eachside thereof, a plurality of overlapping screen frames,

and yieldingly supported pivots on the opposite upper corners of each ofsaid frames vertically slidable in said guides.

5. A window screen including grooved side guides attachable to windowcasings; a screen frame; yieldably supported pivots on said framesfrctionally engaging said guides; a second screen frame overlying thesaid first mentioned frame, and having extension pivots frictionallyengaging the same groove that guides said first frame.

6. A window screen including grooved side guides attachable to windowcasings, a screen frame, a friction shoe slidable in the groove of saidguide and having a stem engaging said frame, a resilient memberinterposed between said shoe and frame, and a pivot on the opposite sideof said frame slidable in the guide on that side of the window casing, asecond screen frame overlying said first frame and having an extensionspring pivot engaging the same groove that guides the first frame.

7. In a window screen a frame composed of four strips joined at thecorners, a groove in the face of said frame, a sheet of netting havingits edges confined in said groove, angular metal strips having a barbedflange edge forced into said groove on top of said netting, and metalcorner plates attached to said frame overlying the adjacent ends of saidmetal strips and inclosing the edges of the frame at the corners.

In testimony whereof, I have hereunto set my hand this 24th day of May,1913.
